Problem with kdb kernel debugger patch against 2.2.19

Hello [e-mail],

  I patched my 2.2.19 kernel with the SGI kdb patch to have the
  ability of kernel debugging and especially debugging of the kernel
  modules I write.
  I had to install libbfd and the kernel seems just to compile perfectly.
  Lateron I get the following error :

  /usr/src/linux # make bzImage

  [...]

make[2]: Nothing to be done for `all_targets'.

   What does
   "/tmp/ccVx3zpC.s:1024: Fatal error: Symbol machine_check already
   defined." mean, how can I solve it to get my kernel with kdb ?

   Note: I'm still using 2.2.19 because of module development to test
   kernel modules for 2.2.x.

   Thanks in advance, Markus
